CTICasesAcute barotrauma presenting as progressive paraseptal emphysema
Imaging findings
CT scan of a 22-year-old non-smoker with DAD following intubation shows rapid development of severe, bilateral paraseptal and centrilobular emphysema/cysts within two weeks, localized to the spared, non-dependent lung regions.
Key takeaways
Barotrauma in patients with severe ARD/DAD can cause rapid, localized alveolar destruction and paraseptal/centrilobular emphysema. This typically occurs in non-dependent, relatively aerated lung zones where ventilation pressures are highest.
